placid Elk_3671 : The question focuses on 'performance'; hence, it is necessary to define what 'performance' means, in relation to real estate.
I think, sufficient supply to meet demand is one key factor. Another would be 'affordability' and what policy is introduced to ensure equitable distribution.
Singapore's property market is affected by high demands and lack of supply. Although the figures for unsold units is the lowest since 2006, this indicates that housing plans underestimated the actual demands. In addition, cooling measures (such as higher duties or increased interest on mortgage) are not mentioned, at all.
Rentals is picking up due to 'employees returning to the office' and 'expected pick-up in business activities', which are non-economics; therefore, unrelated to property market performance.
The UK market, on the other hand, is affected by higher inflation and makes no mention of supply nor demand. Assuming these economic factors remain unchanged, this alone indicates stability in performance. Furthermore, market forces (higher interest rates and cost of living) are likely to improve affordability, and requires no policy adjustments.
Increased mortgage rates on top of rising property prices in the US strains 'affordability', which questions the motivations of the urban planners. Equitable distribution will be hard to achieve, and the homeless is likely to remain so until Lady Fortune smiles down on them, in some form.
Hence, the UK market is – with the available information – showing the best performance.
